Cool!  Thanks.

Yeah, that’s because double-space after period fixes ambiguous cases as
this example: “The author J. R. R. Tolkien wrote The Hobbit. George
R. R. Martin wrote many fantasy books.”  The brain is able to determine
it’s only two sentences, but it becomes more difficult otherwise; it
could count 7 sentences.

Anyway. :-)

For what it is worth, I would suggest something as:

--8<---------------cut here---------------start------------->8---
(map (lambda (v)
       (if (number? v)
           (number->string v)
           (begin
             (pk 'else v)
             (pk (string-append "-" v "0")))))
     '(1 "2" "3" 4))
--8<---------------cut here---------------end--------------->8---

For two reasons:

 1. ’begin’ helps to mark a sequence of expressions; IMHO, that’s a good
     habit when playing with ’pk’ for debugging purpose.

 2. it exposes that ’stuff’ above can be anything.


Well, my suggestion could be two other examples in addition to the
current one instead of the complexification.

My 2 cents. :-)
